(Granted under the act of March 3, 1883, as amended April 30, 1928; 370O. G. 757) Claims.

The invention described herein, if patented may be manufactured and usedby or for the Government for governmental purposes, without the paymentto me of any royalty thereon.

This invention relates to a combined sleeping bag and pack. Th bagconsists of four parts, three of which can be packed in the fourth,which carries flaps and straps by means of which the whole can be foldedinto a compact knapsacktype pack.

In certain types of duty and in certain war theatres, it is necessary toprovide troops with sleeping bags of sufficient warmth to protect themagainst severe cold, which must be carried with the individual solder aspart of his equipment. It is desirable to provide the sleeping bags usedin such intances with an outer layer or cover adapted to protect boththe sleeper and the pack from bad weather, and also with means forforming a pack harness. It is further necessary to combine this articlewith other equipment which the soldier must necessarily carry, in orderthat his total burden may be as small as possible and sufficientlycompact so that it will not interfere with his movements.

It is an object of this invention to provide a sleeping bag pack whichhas four parts, one part in the form of a sack adapted to serve as agarment and also as a container and having flaps which may be fastenedsecurely around the container part, which holds the other parts of theoutfit, to form a pack of knapsack appearance having pockets to carryother articles of the soldiers equipment.

It is a further object of the invention to provide a sleeping bag packconsisting of two warmth providing members, an upper garment and a lowersack-like garment for the feet, and two outer garments of water and windresistant construction, the lower one of which is provided at the bottomwith flaps and straps adapted to form a knapsack pack containing theother three garments.

Further objects of my invention will be apparent from a consideration ofthe specification in connection with the accompanying drawings, inwhich:

Figure 2 is a perspective front view of a modified form of the sleepingbag in pack form.

Figure 3 is a perspective view of the lower outer garment which formsthe container for the other garments, the flaps and straps foldedbeneath it.

Figure 4 is a bottom plan view of the lower from the rear 2 outergarment or sack shown in Figures 1 and 3, the straps and flaps beingextended.

Figure 5 is a side view of the outer weather resistant upper garmentsFigure 6 is a front View of the garment shown in Figure 5.

Figure 7 is a side View of the inner warmth providing upper garment.

Figure 8 is a side view of the lower inner garment.

Figure 9'is a face View of the inner upper garment shown in Figure 7.

Figure 10 is a front view of the inner lower garment shown in Figure 8.

As shown in Figures 1 and 2, the assembled garments of this inventionconstitute a pack which can easily be carried by a soldier in lieu ofthe ordinary knapsack or pack bag, since this equipment takes the placeof blankets and shelter tents which would otherwise have to be carried.The sleeping bag consists of four parts or garments shown separately inthe remaining figures of the drawings. Two inner garments A and B areprovided, made of blanket material or other material of sufiicientwarmth to suit the climate in which the equipment is to be employed. Theupper body garment A includes sleeves It having knitted or otherresilient wrists H and a hood i2 adapted to cover the head of thewearer. The garment A opens down the front and is provided with suitablefasteners such as buttons l3 and button holes M. The lower inner garmentB is made of similar material as garment A; it is preferably ofsubstantial frustoconical shape, open at its base and closed at itsplane of truncation, and equipped with an enlarged foot-receivingportion proximateits closed end, which foot-receiving portion consistsof a single pocket or foot 5, for receiving both feet of the wearer. Itis provied with shoulder straps It by which it may be kept in place butwhich permit it to be easily kicked off in case the wearer is disturbedby some emergency.

As shown in Figures 5 and 6, the outer upper garment C is similar inconfiguration to the inner garment. The sleeves H are not provided withconstrictions at the wrists but are intended to be partly drawn insidethe arm hole to close the exterior of the outfit against weather whenthe wearer is asleep. The garment C is provided with a draw string It atthe bottom and a drawstring i9 around the face opening of the hood 20.It is partly open down the front and the opening 2| is provided withbuttons 22 or other suitable fasteners.

around the face of the The outer lower garment D consists of a sack 23having a draw string 24 at top which is adapted either to tie around thewaist of the wearer or to close the sack on its contents when it is usedas a pack sack. The sack 23 is substantially the same size throughoutits length and has a flat bottom 25 which forms the back contactingmember of the pack and shapes and supports the pack so that it has theappearance of a knapsack. To three edges of the bottom forming memberthere are attached flaps which serve to enclose the folded sack 23. Oneflap 26 is attached at the top of the sack bottom or back form-ingmember 25 and is adapted to be folded forward over the top and down theface of the pack- Itis secured by buckles 21 to the straps 28 which areattached to the opposite edge of the back member 25 and which areextended around the lower side of the pack before being buckled to theflap 26. The flap 26 carries a compartment formed of telescoping members29 and 39 and closed by a buckled strap 3! secured at its ends to thetelescoping members. Because the flexible pocket forming elements 29 and3!] are secured to the flap 25 with their free edges in overlappingrelation, the open ends may be inserted one intothe other in telescopingfashion to close the compartment. The flap 26 also carries an attachmentmember 32 which may carry a bayonet or other elongated member.

The side flaps 33 are attached to the sides of the back formingmember'25 and are folded pack beneath the top flap 25. Either or bothside flaps 33 may carrypockets 34, 35 for miscellaneous items ofequipment such socks, rations, maps, etc. The two flaps 33 are securedtogether by straps 3b fastened by buckles 37. The form of pack shown inFigure 1 has one pocket 35, while that shown in Figure 2 has two pockets34 and 35.

To the top of the back member 25 is secured a pack harness comprising awebbing 33 which forms shoulder strapsfor the pack and which are securedto the lower members 39 attached to the bottom of the back member 25,suitable provisions for adjustability being made. The supporting member40 is also attached to the member 25 for carrying any desired articles,as a mess i c.

In using this sleeping bag and pack a soldier will be protected at nightboth from cold and from wind and storms. The lower members B and D,which interfit when the sleeping bag is extended for use, are secured inplace by the shoulder straps I E and draw string 24 respectively withsufiicient firmness to insuretheir remaining in place during the night,but both can be removed quickly in case of emergency. When the soldieris to move on, he folds the two inner garments A and B and upper outergarment C and places them in the bottom of the sack D which is thefourth member of the sleeping bag assembly. In this sack D he may alsoplace such other articles of his equipment as cannot be accommodated inthe various pockets and compartments of the pack flaps 26 and 33. Hethen folds down the top of the sack as tightly as possible, and drawsthe side flaps 33 around the sack and its contents, buckling the straps36 securely. the top flap 26 over the top end face of the sack andsecures it by the straps 23. When he has placed his smaller articles ofequipment in the pockets 34 and 35 and compartments 29, 30 of the flaps,he is provided with a unitary piece of Finally he brings adapted toenclose and protect the lower part of the body of the wearer and havinga flat bottom,
